Criminal justice client rehabs can be considered being a considerably better option than incarceration or significant fines for those who have been convicted of any kind of alcohol or drug related crime. For instance, someone who has been in prison for driving while impaired of drugs or alcohol may be eligible for rehabilitation services because of their problem as opposed to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or in addition to other consequences. First time offenders in particular will often be given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it if it is an option. The concept behind criminal justice client rehabs is that it is way more efficient and effective to invest commitment into treatment than enforcement of other consequences. Much research has been completed to observe how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who take part in rehabilitation have a better probability of remaining out of the system after rehab.
